A Health Savings Account Lets You Set Aside Pre-Tax Money for Medical Costs

A Health Savings Account (HSA) is a bank account where you deposit money before taxes are taken out of your paycheck, then withdraw it to pay for medical expenses. The money you put in reduces your taxable income for the year. When you withdraw funds to pay for may have access to medical costs—doctor visits, prescriptions, dental work, vision care, medical equipment—that withdrawal is also tax-free. You keep any money you don't spend; it rolls over to the next year and earns interest or investment returns.

To open an HSA, you must be enrolled in a high-deductible health plan (HDHP)—a type of health insurance with lower monthly premiums but a higher deductible (the amount you pay out of pocket before insurance kicks in). You cannot have an HSA if you are covered by other health insurance, Medicare, or claimed as a dependent on someone else's tax return. The account is yours to manage; you choose the bank or investment provider, and you decide how much to contribute each year, up to a federal limit.

Key Takeaways

  • Money deposited into an HSA is not subject to income tax, and withdrawals for may have access to medical expenses are also tax-free.
  • You must be enrolled in a high-deductible health plan to open or contribute to an HSA, and you cannot have other health coverage at the same time.
  • Unused HSA funds roll over year to year and can be invested to grow; there is no "use it or lose it" deadline.
  • After age 65, you can withdraw HSA funds for any reason without penalty, though non-medical withdrawals are taxed as income.
  • may have access to medical expenses include doctor visits, prescriptions, dental, vision, hearing aids, and some medical equipment, but not insurance premiums or over-the-counter items without a prescription.

How Money Goes In: Payroll Deduction or Direct Contribution

If your employer offers an HSA, the easiest route is payroll deduction. Your employer deducts a set amount from each paycheck before taxes are calculated, and that money goes directly into your HSA. You see the reduction in your gross pay, which lowers your federal income tax bill for the year. You decide the amount each year, usually during open enrollment, and can change it once per year or when your coverage changes.

If your employer does not offer an HSA or you are self-employed, you can open an account at a bank, credit union, or investment firm and make direct contributions yourself. You deposit money after you receive your paycheck, then claim the deduction on your tax return (Form 1040, Schedule 1). The tax benefit comes at tax time rather than on each paycheck, but the result is the same: the contribution reduces your taxable income.

The IRS sets annual contribution limits. For 2024, the limit is $4,150 for individual coverage and $8,300 for family coverage. If you are age 55 or older, you can contribute an additional $1,000 per year. Contributions must stop by the tax filing deadline (usually April 15) to count toward that tax year.

What Counts as a may have access to Medical Expense

may have access to expenses are medical, dental, vision, and hearing costs that treat or prevent illness or injury. Doctor office visits, hospital stays, surgery, lab tests, X-rays, and mental health counseling all may have access to. Prescription medications may have access to; over-the-counter drugs do not unless you have a prescription from a doctor. Dental work—cleanings, fillings, root canals, orthodontics—qualifies. Vision care including eye exams, glasses, and contact lenses qualifies. Hearing aids and related services may have access to.

Some items that do not may have access to: health insurance premiums (with three exceptions: COBRA continuation coverage, long-term care insurance, and Medicare premiums after age 65), cosmetic procedures, gym memberships, vitamins without a medical condition diagnosis, and over-the-counter pain relievers or cold medicine without a prescription. If you are unsure whether a specific expense qualifies, the IRS publishes a detailed list on its website, and your HSA provider can also answer questions about specific items.

You do not have to withdraw money the same year you incur the expense. You can pay a medical bill out of pocket and withdraw the same amount from your HSA months or years later, as long as you have receipts showing the expense was incurred while you had an active HSA. This flexibility lets you leave money in the account to grow if you do not need it immediately.

How Withdrawals Work and What Happens to Unused Money

To withdraw money, you request a transfer from your HSA to your checking account, write a check from the HSA account itself, or use an HSA debit card if your provider offers one. Some providers let you submit a receipt and request reimbursement directly. There is no annual deadline to spend the money; unused funds stay in the account indefinitely and roll over to the next year. This is different from a Flexible Spending Account (FSA), which has a "use it or lose it" rule.

If you withdraw money for a non-may have access to expense before age 65, you owe income tax on the withdrawal plus a 20 percent penalty. For example, if you withdraw $500 for a non-may have access to expense and your tax bracket is 22 percent, you owe $110 in tax plus $100 in penalty—a total of $210 on top of the $500 you withdrew. After age 65, the 20 percent penalty goes away, but you still owe income tax on non-may have access to withdrawals.

Many HSA providers offer investment options—mutual funds, stocks, bonds—so your balance can grow over time. Some accounts require a minimum balance (often $1,000 to $2,500) before you can invest; below that, the money sits in a cash account earning little or no interest. If you invest HSA funds and the investment loses value, you absorb the loss, just as you would with any investment account.

HSA Ownership and What Happens When You Change Jobs or Insurance

The HSA belongs to you, not your employer. If you leave your job, the account stays open and the money remains yours. You can continue to use it to pay for may have access to medical expenses, and you can continue to contribute to it if you remain enrolled in an HDHP (whether through a new employer or the individual market). Your new employer cannot take the money or force you to move it; you control the account.

If you drop your HDHP coverage and enroll in a different type of health plan, you can no longer make new contributions to the HSA. However, you can still withdraw money from the account for may have access to medical expenses incurred while you had the HDHP. Once you re-enroll in an HDHP, you can resume contributions. If you enroll in Medicare, you can no longer contribute, but you can still withdraw for may have access to expenses.

Some employers offer HSA custodians or administrators who handle the account on your behalf. Even so, the account is yours. If you leave, you can transfer the balance to an HSA at another bank or provider. The transfer is tax-free and does not count against your annual contribution limit. You have the right to move your money without penalty.

Tax Reporting and Record-Keeping

HSA contributions made through payroll are reported on your W-2 form and automatically reduce your taxable income. If you made direct contributions, you report them on Form 8889 (Health Savings Accounts) when you file your tax return. Withdrawals for may have access to expenses do not need to be reported on your tax return, but you should keep receipts and documentation in case the IRS asks questions.

Your HSA provider sends you a statement each year showing contributions, withdrawals, and interest or investment gains. Keep these statements along with receipts for medical expenses. The IRS can audit HSA accounts, and if you cannot document that a withdrawal was for a may have access to expense, you may owe tax and penalty on that amount retroactively. Good record-keeping protects you if an audit occurs.

If you withdraw money and later realize it was not for a may have access to expense, you can put the money back into the account (called a recontribution) within a limited time frame. Rules vary by provider, so ask your HSA administrator about their recontribution policy if you make a mistake.

Frequently Asked Questions

Can I use my HSA to pay for my spouse's medical expenses?

Yes, as long as your spouse is claimed as a dependent on your tax return. You can also use HSA funds for the medical expenses of any dependent you claim, including children and parents. The expense must still be may have access to; the dependent status is what matters for may be able to access.

What happens to my HSA if I die?

The account becomes part of your estate. If your spouse is the beneficiary, they can continue to use the account as an HSA and withdraw for their own may have access to expenses. If a non-spouse inherits the account, it is treated as income and subject to tax, though they can still withdraw for the deceased person's unpaid medical expenses without penalty.

Can I use my HSA to pay for dental or vision insurance premiums?

No. Dental and vision insurance premiums do not count as may have access to expenses. However, you can use your HSA to pay for the actual dental work (fillings, crowns, orthodontics) and vision care (eye exams, glasses, contacts) once you have paid the premium out of pocket.

Do I have to spend my HSA money every year?

No. Unlike a Flexible Spending Account, there is no deadline to use HSA funds. Money rolls over year to year indefinitely. You can let the balance grow and use it whenever you need to pay for may have access to medical expenses, even decades later.

What if I withdraw money and then find out it was not a may have access to expense?

You owe income tax and a 20 percent penalty on the withdrawal (before age 65). Some HSA providers allow you to recontribute the money within a short window if you catch the mistake quickly, but this depends on the provider's rules. Contact your HSA administrator immediately if this happens.
